My periods came in july 25 and end 27, after that continuous spotting till next period which came 23 august ends on 25th august. Again spotting started. Its brown in color. Like 2-3 drops in a day. I have PCOS and I took ipill on 9 july after 10-12 hour of unprotected sex (june period came on 28 ends on 39th june) Does this mean I am pregnant? Whats wrong?
